hey guys and gals. just learning lighting and got a good grasp. i am know looking into building a light from scratch i know a bunch about par and spectrum and other things but im still trying to figure out how to read led chip descriptions. i know you need forward voltage to know how many chips a driver will push. i know you dont want to exceed the max amps and the higher amps you push the more cooling you need. what i dont understand is on the digi key site were it has the whole description. it tells you the lumens per watt but not the max wattage if that makes sense. for example if it says 36 forward volts and max amps 2.0 that means i could have a 80 volt driver that is 1.5 amps push 2 of these chips am i correct . the part were im confused is how many watts will these chips be or how many lumens will it produce at this amps. with out the total watts i cant know the max lumens. i just need to know so i can know if i will be buying 4 chips or 400 chips to get a 2x4 room filled. im going to put a link to an example page any help is greatly appreciated.https://www.digikey.ca/product-detail/en/cree-inc/CXA2530-0000-000N0HU240G/CXA2530-0000-000N0HU240G-ND/5301437?utm_adgroup=&mkwid=sf4bcuAaz&pcrid=311509559966&pkw=&pmt=&pdv=c&productid=5301437&slid=&gclid=Cj0KCQjw1MXpBRDjARIsAHtdN-1-gTony89tQKlPjCtSvYtrW-EXN1aJG7AtkseYtAeurLb-VIPgra0aAn9FEALw_wcB
Hope this goes to correct spot !!! I’m using just 1 600 watt LED only have 3 plants in this particular tent 5x5 there flowering good but bottom limbs aren’t getting enough lux or something is up with this 1 light I have, anyway you think the 600 watt light could be the problem? Thanks Okla Grower
I have a question. I will be starting my outdoor grow indoors and transferring them outdoors in May as usual. This year I will be growing auto AND quick flowering, photo plants. I will be using T5 lights until the transfer.
Any advice for the the time schedule too use? I know 18/6 is standard, but I don’t have two light rooms to separate the plants, so they will be in one room until the transfer. 18/6 is fine for the photo, but will the schedule have a detrimental affect on the auto’s yield? . . . thanks for your advice
Has anyone tried Kogan LED Lights?
Hi there, I too am a total noob. I am looking at getting a Kogan Tent and noticed they also have LED.
I’m just a poor boy so I don’t have a lost of cash to throw around.

Hi everyone!
I’m on my first grow, I’m looking for a cheap led light for a micro grow box (50×50×80)cm.
Which one is better:
- 50w / 6000k or 3000k / 4250lumen
- 100w / 6000k or 3000k / 8500lumen
They’re both made with smd2835 chips led
Peace✌
Hi Folks, I’m new here and mostly a micro dwarf grower, so I have been testing these AMAZON "ECRU 150 or 200 watt /Full Spectrum and Blurple LEDs (Act. wattage 27-35) " with one (1) 26 watt, CFL in the Unique Hydroponics 2x2x3’ cabinet.
Q.1. . "When Growing IN VERY TIGHT SPACES can Sunshade (fly) screen be used to reduce light intensity when the plant’s canopy height can NOT be adjusted anymore to compensate ? tHE configuration has a fixed height of 36 inches?
Seriously, no other choices but to use CFLs if not.
Oh, btw works pretty good since I upgraded to quiet, USB i/o fans and a cool, floor air intake.
Appreciate any help, thoughts?

No! You would be circulating used air. You need fresh air, full of CO2
ya agreed
Can someone tell me how big of a carbon filter/exaust fan to get 4" or 6" ?? I have a 7’X4’X6’ grow room using 1 600 watt HPS light (Ipower) and 1 1200 Watt LED light (King LED) in the room. I couldnt find where to post a question…Please help

Guys and Gals! I am new to this “tent growing”… I have a 4 x 8 and have no clue what lights to buy or where to buy them. I am going to try ten plants, is that to many, not enough? Your help would be greatly appreciated
Light got in during lights out time plants in veg.
Light from tv when door was left open, specifically. Will that make them herm or do any other type of damage?
I’m using CSNJ Technologies photon board led grow light, power is 320W, price is 180USD, high performance and cost-effective. Maybe this information can help you.
any remedies for odor control?
Hey guys I have a question regarding lighting.
During flowering, it’s getting a bit hot.
2 lights on, my question is, can I hook secondary light up to my temperature controller, so it goes off when too hot, and on when too cold. This means my secondary light will go on and off several times each day, is this bad for the bulb? Is this bad for the plants even though primary light is undisturbed? Thanks guys
